I have just upgraded my WordPress site from 2.0 to 2.5. Everything went pretty well as far as I can see it and it is working as expected... except for the SECRET_KEY new feature.
By default, I had not it in my wp-config.php, and all went well. Yet when I added the right line, I had of course to reconnect my user in order to access the admin pages. And then when I log in, I get the message "You do not have sufficient permissions to access this page.".
For information, the user logging in is the administrator of the blog. I have searched the site and the forum for a similar case, but did not find such. Would someone have an idea to help me please? I can have my blog admin work as long as I don't enable this new feature, but as this is a security enhancement, it would be a shame not to use it! :-/
